Identify the following objects as being either ...
a. positive     b. negative      c. neutral
If there is no conclusive evidence, then select all that could be true and put them in alphabetical order. So if you think it can be both positive and neutral you would write ac

Description of Object
i. An object possesses more protons than electrons._______ 
ii. An object possesses more neutrons than electrons._______ 
iii. A formerly neutral object that just lost some electrons._______ 
iv. A formerly neutral object that just gained some electrons._______ 
v. An object that attracts a negatively charged balloon._______ 
vi. An object that attracts neutral paper bits and attracts a negatively-charged balloon._______ 
vii. An object that attracts neutral attracts paper bits and repels a negatively-charged balloon._______ 
viii. An object that attracts a negatively-charged balloon and attracts a positively-charged   balloon._______ 
ix. An object that attracts a charged balloon (balloon A) which is attracted to a negatively-charged balloon (balloon B)._______ 
x. An object that attracts a balloon (balloon C) which is repelled by a negatively-charged   balloon (balloon D)._______ 
xi. An object that repels a balloon (balloon E) which is repelled by a positively-charged   balloon (balloon F)._______ 
xii. An object around which the electric field vector is directed inwards._______ 
xiii. An object around which the electric field vector is directed outwards._______
